This invention relates to brake shoes, and

is illustrated as embodied in a pressed-metal brake shoe for an internal expanding automobile brake. An object of the invention is l to rovide inexpensive and secure means for he ding the brake lining, by punching prongs out of the pressed metal ofthe shoe and clinching them over in the lining. Preferabl the shoe is made in two parts secured to toget er, with a separate series of prongs in each part.

The above and other features of the invention will be apparent from the following description of one. illustrative embodiment ll shown in the accompanying drawing, in

which:

.Fig. 1 is a side elevation of one form of shoe embodying the invention;

Fig. 2 is a section through the shoe on the 80 line 2-2 of Fig. 1; and

Fi 3 is a partial section through a difier'-' ent s cc, on a plane corresponding to the line 3-3of Fig. 2.

The particular shoe selected for illustrali tion is fully described in Patent No.- 1,567,716, granted Bendix Brake Company on December 29, 1925, on an application filed by Adiel Y. Dodge, although the invention is also applicable to shoes of other 80 types. This shoe includes two stampings nerally L-shaped in cross-section, and in-' cluding cylindrical flan es 10 and 12 extendin away from each 0t er and forming the friction face, and radial flan es 14 and 16 88 riveted or other wise secure together to form the stiffening web. At one end of the shoe there may be a cam plate 18, while at the other end of the flanges 14 and 16 may extend beyond the friction face of the shoe (0 to form anchorin arms 20.

- According to t e present invention, each 'of the flan 10 and 12 is provided with linin -attac ing means, preferablly by punc 'ng out transverse rongs 22 ig. 2) 6 or longitudinal prongs 24 Fig. 3), adapted to be bent and clinched overh} a suitable tool 26 into the lining 28, the lining being drilled or' punched with the holes necessary for the p While one illustrative embodiment has been described in detail, it is not my intentlon to limit the scope of the invention to that particular embodiment, or otherwise than by the terms of the appended claims.

I claim:

1. A brake shoe of pressed metal in two parts secured together approximately in the central plane of the shoe, with lining overlying both of said arts, each part being formed with integral prongs bent back on themselves and clinched in the i 2.

3. A T-section brake shoecompris' twocomplementary pressed metal L-sha sections secured together back to bac with their axial flanges arranged in the same circumferential plane and provided with a lining extending thereover, each of said flanges being punched out to provide prongs which project through the lining and are clinched down therein to secure the lining to the shoe.

4. A brake shoe comprising an integral,

'sclf-supportin metal structure having a circumferential lining supporting member provided 'with a linin and, with portions punched therefromt ugh the lining to secure the same to the shoe.

5. A brake shoe consisting of an integral self-supporting sheet metal structure provided with a radially extending portion formed to receive a support at one end and a circumferentially extending portion provided with a brake lining secured thereto by prongs punched therefrom throughthe lining. e 6. A brake shoe havin a radially extending stiffening portion and a circumferential 1y extending lining supportin portion formed of the same piece of meta and provided with a lining secured to its circumferentially extendin portion by prongs punched therefrom t rough the lining.
